Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction, in particular to a pre-embedded positioner for a preset hole in a building structure. Background Art
[0002] As we all know, in construction, different structural forms will be constructed, among which preset holes are a commonly used one. They can be pre-positioned and installed during construction, and positions can be reserved to facilitate the subsequent installation of other components.
[0003] However, when locating the preset holes in existing buildings, most of them use simple embedded locators, which are fixed on the building for embedded positioning. The existing embedded locators have a simple structure and cannot be adjusted according to the embedded holes of different diameters. The embedded locators can only be fixed on the building with the same diameter as the embedded holes. The practicality is poor, and a new locator needs to be proposed. Utility Model Content
